Autocare Universal Bulb Kit £2.50 @ Tesco
After visiting Halfords where they wanted £9.99 for one H7 headlamp bulb, my next stop was Tesco garage, where I picked up a Autocare Universal Bulb Kit which included the bulb I wanted and several others for £2.50, apparently half price .
Noticed they are showing online also, so should be available in most Tesco stores and garages.
